Question

I’m using [self presentModalViewController:head animated:NO]; in ios 4.3 and looking for an alternative for ios 5 and up. I’d prefer using something universal for all iOS versions but if (iOS is lower than 6) can also be great.
My problem is that using [self presentViewController:head animated:YES completion:nil]; as an alternative would work only if animated is set to YES. Any idea why? I don’t want it to animate. Is there anything else I can use if I’m not using StoryBoards ?

Answer 1

Does the app fail at all? Have you got NSZombies enabled?

If you are doing something like this

- (id)init {
    self = [super init]

    if (self) {
       ViewController * viewController = [[ViewController alloc] init];
       [self presentViewController:viewController animated:YES];
    }

    return self;
}

This is because the view hasn’t initiated yet please use one of the following methods

- (void)viewDidAppear:(BOOL)animated {
   [super viewDidAppear:animated];

   ViewController * viewController = [[ViewController alloc] init];
   [self presentViewController:viewController animated:YES];

}

// OR

- (void)viewDidLoad {
   [super viewDidLoad];

   ViewController * viewController = [[ViewController alloc] init];
   [self presentViewController:viewController animated:YES];

}

I understand that this might not answer your question but you did not post what initiator it is in. But this is a common error so thought I would post incase it solves your problem.
